  2. Signal transduction - Wikipedia

    en.wikipedia.org/wiki/Signal_transduction

    How to read signal transduction diagrams, what does normal arrow and flathead arrow means. Elements of Signal transduction cascade networking. Following are some major signaling pathways, demonstrating how ligands binding to their receptors can affect second messengers and eventually result in altered cellular responses.

  3. Cell signaling - Wikipedia

    en.wikipedia.org/wiki/Cell_signaling

    The signal transduction component labeled as "MAPK" in the pathway was originally called "ERK," so the pathway is called the MAPK/ERK pathway. The MAPK protein is an enzyme, a protein kinase that can attach phosphate to target proteins such as the transcription factor MYC and, thus, alter gene transcription and, ultimately, cell cycle progression.

  4. List of signalling pathways - Wikipedia

    en.wikipedia.org/wiki/List_of_signalling_pathways

    In cell biology, there are a multitude of signalling pathways. Cell signalling is part of the molecular biology system that controls and coordinates the actions of cells.. Akt/PKB signalling pathway

  5. Biochemical cascade - Wikipedia

    en.wikipedia.org/wiki/Biochemical_cascade

    Two main signal transduction mechanisms have been identified, via nuclear receptors, or via transmembrane receptors. In the first one, first messenger cross through the cell membrane, binding and activating intracellular receptors localized at nucleus or cytosol , which then act as transcriptional factors regulating directly gene expression.

  6. Insulin signal transduction pathway - Wikipedia

    en.wikipedia.org/wiki/Insulin_signal...

    Signal transduction is a mechanism in which the cell responds to a signal from the environment by activating several proteins and enzymes that will give a response to the signal. Feedback mechanism might involve negative and positive feedbacks. In the negative feedback, the pathway is inhibited and the result of the transduction pathway is ...

  7. Upstream and downstream (transduction) - Wikipedia

    en.wikipedia.org/wiki/Upstream_and_downstream...

    There are three kinds of contextual factors that determine the shape the TGF-β response: the signal transduction components, the transcriptional cofactors and the epigenetic state of the cell. The different ligands and receptors of TGF-β are significant as well in the composition signal transduction pathway. [2]

  8. JAK-STAT signaling pathway - Wikipedia

    en.wikipedia.org/wiki/JAK-STAT_signaling_pathway

    The Janus kinase (JAK)/signal transducer and the activator of the transcription pathway were at the centre of attention for driving hyperinflammation in COVID-19, i.e., the SARS-CoV-2 infection triggers hyperinflammation through the JAK/STAT pathway, resulting in the recruitment of dendritic cells, macrophages, and natural killer (NK) cells, as ...

  9. Cell surface receptor - Wikipedia

    en.wikipedia.org/wiki/Cell_surface_receptor

    If the membrane receptors are denatured or deficient, the signal transduction can be hindered and cause diseases. Some diseases are caused by disorders of membrane receptor function. This is due to deficiency or degradation of the receptor via changes in the genes that encode and regulate the receptor protein.
